PATENT OFFICE Y., ASSIGNOR 0F ONE-HALF TO JOHN C.

ZULEGER, OF GREAT KILLS, NEW YORK LAMP SHADE Application filed. May 11, 1928.

This invention relates to improvements in lamp shades and has particular reference to a supporting frame therefor.

One object of the invention is to provide an improved frame of simple and practical con struction capable of supporting shades of the flexible type such as those made of plaited parchment paper or the like.

Another object is to enable the shade to be securely mounted in a fixed position on its frame by providing the latter with a plurality of supporting members with which different portions of the shade are adapted tocontact.

Another object is to provide a frame of Slln pleconstruction upon which the shade can be readily and quickly mounted.

The above objects will appear more clearly from the following description when taken in connection with the accompanying drawing which illustrates a preferred embodiment of the inventive idea.

In the drawing:

Figure 1 is a fragmentary vertical section of a lamp shade constructed in accordance with the invention.

Figure 2 is a top ing frame.

Referring more particularly to the accompanying drawing, 3 indicates a plaited lamp shade of known construction made of parchment paper or the like. The shade is formed from a single sheet of. material having its ends secured together by any suitable means plan view of the supportr and the body of the shade being creased transversely to provide a plurality of plaits to en able the shade to be readily collapsed when not in use and to be extended into substantial frusto-conical formation when placed upon its supporting frame.

Extending around the shade adjacent its upper end and through the plaits thereof is a draw cord 10 or other flexible element, the ends of which may be pulled after the shade has been mounted upon the frame, to constrict Serial No. 276,870.

the upper end of the shade and thereby cause it to contact with the frame in a manner to presently appear. After this is done, the ends of the cord may be tied to securely hold the shade in position.

The frame is of a general frusto-conical shape constricted intermediate its upper and lower ends to provide in. effect upper and lower opposed frusto-conical portions. To this end, the frame comprises upper intermediate and lower ring members 4, 5 and 6 respectively, made of wire or the like, the upper member being of greater diameter than the intermediate member, and less in diameter than said lower member. In order to maintain said ring members in spaced concentric connection, they may be opposed by braces 7 which converge upwardly between, and are secured to, rings 5 and 6. From the ring 5,

the braces are extended upward a slight distance and then bend outwardly at an incline to the upper ring 4 to which they are also secured.

The upper ring 4: may be provided with a lamp holder consisting of an arm 8 extending inwardly from and in the plane of said ring and having its free end bent into a loop 9 which rests upon the bulb of an incandescent lamp and whereby the lamp shade is supported on said bulb.

To mount the shade 3 in position on the frame, the latter is inserted into the lower end of the shade and moved'upwardly to the opposite end so that the upper ends of the plaits will abut the upper ring with the outer edges of said plaits disposed outwardly beyond said ring, the widths of the plaits being greater thanthe difference in the diameters of the rings 4 and 5. The inner edges of the plaits now rest against the rings 5 and 6 and the ends of the cord may now be pulled and tied so as to fix the shade in position. In this manner the frame forms, in effect, a three point suspension for the shade.

It is to be noted that in constructing the frame, the diameter of the lower ring may be made different from that shown so as to Vary the configuration of the shade when mounted on the frame, or, in other Words, change the inclination of the plaits.

What is claimed is:

The combination with a plaited lamp shade of a supporting frame including an upper ring member contacting the upper ends of the plalts of said shade, an intermediate ring member engaging the inner edges of said plaits adjacent said ends thereof and a lower ring member also engaging said inner edges at points below said intermediate member.
